Abstract

There is concern about sustainable management of stocks of reef fish, particularly as we do not fully understand population dynamics and response to harvest of many species (Mapstone et al. 1997 ). Evidence to date suggests that most harvested species have restricted movement ranges ( Davies 1995). Genetic diversity may be reduced if particular populations are over-harvested. To effectively manage fishing in the Great Barrier Reef (GBR), managers require information on the stock structure and gene flow among populations of harvested species along the GBR. This will allow managers to balance conservation of biodiversity with sustainable exploitation. Genetic markers are useful in determining stock structure of fish and assessing gene flow among populations (e.g. Wright & Benzen 1994). The lack of suitable genetic markers is an impediment to our understanding of the population structure of tropical reef fish.
